A luggage handle structure includes two pull rods having linkage rods therein, a handle unit connected between the two pull rods and having an accommodation hole leading to two ends thereof, and a press unit. The press unit includes a press rod assembly which is movably disposed in the accommodation hole. The press rod assembly has two ends as press portions which are exposed out of the accommodation hole and push portion corresponding in position to the two pull rods. Each push portion has two first inclined planes to form a V shape against the upper end of the corresponding linkage rod. No matter either press portion is pressed, the push portions of the two ends will push the two pull rods simultaneously to release a locking mechanism.

1. A luggage handle structure, comprising: two retractable pull rods for coupling to a luggage, each pull rod being a hollow rod and comprising a movable linkage rod therein, a push rod connected to a lower end of the linkage rod, and a locking mechanism connected to a lower end of the push rod;a handle unit connected between the two pull rods, one end of the handle unit being coupled to one pull rod and another end of the handle unit being coupled to the other pull rod, the handle unit having an accommodation hole therein, the accommodation hole leading to the two ends of the handle unit; anda press unit disposed in the handle unit, the press unit comprising a press rod assembly and at least one elastic member, the press rod assembly being movably disposed in the accommodation hole of the handle unit, two ends of the press rod assembly having press portions exposed out of two ends of the accommodation hole and push portions corresponding in position to the pull rods, each push portion having two symmetrical first inclined planes, the two first inclined planes being against an upper end of the linkage rod, the at least one elastic member each having a first elastic end coupled to the handle unit and a second elastic end against the press rod assembly;whereby when either of the press portions is pressed, the press rod assembly is retracted against the at least one elastic member, causing the upper end of each of the linkage rods to move along the first inclined planes of the corresponding push portion, thereby pushing down the connected push rod to unlock a locking member of the connected locking mechanism, thus allowing both pull rods to be extended or retracted; and when the press portion is released, the press rod assembly is returned to the original position by the at least one elastic member. 2. The luggage handle structure as claimed in claim 1, wherein the two first inclined planes form a V shape. 3. The luggage handle structure as claimed in claim 2, wherein the upper end of the linkage rod has two second inclined planes, and the two second inclined planes form a V shape. 4. The luggage handle structure as claimed in claim 1, wherein the press rod assembly has a recess at one side thereof, the at least one elastic member comprises two spiral springs accommodated in the recess, one end of each spiral spring is the first elastic end, another end of each spiral spring is the second elastic end, the first elastic end is held in the accommodation hole of the handle unit, and the second elastic end is against one end of the recess. 5. The luggage handle structure as claimed in claim 4, wherein a fixing seat is provided at the center of the accommodation hole, and two ends of the fixing seat have protruding posts for connection of the first elastic ends of the two spiral springs. 6. The luggage handle structure as claimed in claim 1, wherein one side of the press rod assembly has an axial limit hole, and the handle unit has a limit post disposed in the accommodation hole to be inserted in the limit hole. 7. The luggage handle structure as claimed in claim 1, wherein the press rod assembly comprises a slide rod and two buttons, the slide rod is movably disposed in the accommodation hole, the two buttons are connected to two ends of the slide rod, outer ends of the two buttons function as the press portions and are exposed out of the accommodation hole, the two buttons have the push portions corresponding in position to the pull rods, and the second elastic end of the at least one elastic member is against the slide rod. 8. The luggage handle structure as claimed in claim 7, wherein the outer end of each of the two buttons has a hole and a brand block coupled to the hole. 9. The luggage handle structure as claimed in claim 7, wherein two ends of the slide rod each have a first concave portion and a first convex portion, and each of the two buttons has a second convex portion to engage with the first concave portion and a second concave portion to engage with the first convex portion so that the two buttons are connected to the slide rod. 10. The luggage handle structure as claimed in claim 7, wherein the slide rod has a recess at one side thereof, the at least one elastic member comprises two spiral springs accommodated in the recess, one end of each spiral spring is the first elastic end, another end of each spiral spring is the second elastic end, the first elastic end is held in the accommodation hole of the handle unit, and the second elastic end is against one end of the recess. 11. The luggage handle structure as claimed in claim 10, wherein a fixing seat is provided at the center of the accommodation hole, and two ends of the fixing seat have protruding posts for connection of the first elastic ends of the two spiral springs. 12. The luggage handle structure as claimed in claim 7, wherein one side of the slide rod has an axial limit hole, and the handle unit has a limit post disposed in the accommodation hole to be inserted in the limit hole. 13. The luggage handle structure as claimed in claim 1, wherein the handle unit comprises an inner pipe and an outer pipe, the inner pipe is composed of two connected semicircle pipes, the accommodation hole is formed inside the inner pipe, the outer pipe is a one-piece cylinder, and the outer pipe is fitted on the inner pipe. 14. The luggage handle structure as claimed in claim 13, wherein two ends of the inner pipe are exposed out of the outer pipe, and the two ends of the inner pipe are respectively coupled to the pull rods. 15. The luggage handle structure as claimed in claim 14, wherein an upper end of each of the pull rods is connected with a handle connector, the handle connector is formed with plastic, and the handle connector comprises an insertion rod which is inserted into the corresponding pull rod, a head portion formed on top of the insertion rod, and a transverse through hole formed in the head portion for connection of the handle unit.
